i WINDOW.

To all whom it may concern:

Be it known that I, ALFRE J. ELLIS, a citizen of the United States, anda resident of Woodcliff-on-Hudson, in the county of Hudson and State ofNew Jersey, have invented certain new and useful Improvements inWindows, of which the following is a s ecification. he subject. of thepresent invention is a window and a window frame of sheet metal, theconstruction beingvsuch that the parts are assembled and connected in anextremely simple, durable and comparatively inexpensive manner, and the.structure generally present a highly'finished and attractive appearance.

The construction of the sashes are such. that when closed, their meetingrails rovide an absolute air tight joint and avoid a l tendency torattling.

There are otherspecial features connected with the invention which inaddition to those alluded to are clearly explained inthe subse uentdetailed description.

n the accompanying drawing forming part of this specification,Figure 1is a vertical central sectional view of a window frame and sashesdisclosing one form of my invention, the sashes being represented in.

the closed position, this view being broken away at two places in orderto provide for enlarged illustration. Fig. 2, is an enlarged sectionalplan view of one of the sides of the window frame and through portionsof both window sashes, the lower sash being in, the raised osition.

, The intel A, of the window frame is in the hollow sheet metal formindicated in Fig. 1, and provides the two depending offsets a and abetween which the top rail B of the upper sash, bears when said sash isin its raised position. Intermediate of the offsets a and a the bottomof the lintel presents horizontal portions a which merge in the verticalangular rib a the sides of which converge to the apex. It will beunderstood that the offsets (land a, as well as the horizontal portionsa and angular rib a all extend the width of said to members A of t ewindow frame appropriately connect with the lintel attheir upper endsand thefront of said side members, as a well as at the front of thelintel, may be shaped to present a molding 'or ornamental character.

The sill portion A of the frame comprises rail B. The vertical sidePatented Feb. 9, 1909.

a transverse section of sheet metal which'is bent to provide the frontand rear dependin walls a a and theto a". r The sheet meta sectionforming said si 1 ortion is also shaped to present the rear sha owshoulder a, the

short forwardly incline a leading therefrom and the shoulders a, a; Itis desirable that the sill portion A contain a filling a of cement orother suitable composition for imarting solidity to the base of the.window rame.

The vertical rails B of both the upper and lower sashes are each shapedas indicated in Fig. 2 and consist of a section of sheet metal bent toform the front and rear inwardly extending sides 6 and the U-shapedbearing B for the reception of the vertical side edge of the window paneC of the sash. The side portions b, b, terminate in free edges 6 whichare received and slide Within vertical bends each side member of thewindow frame is pre-,

sented by an independent sheet metal section A shaped to provide thebends a, a, and

that the bends a are so conditioned that their recesses are more liberalthan are those of the bends a. This arrangement rovide's for thereception of the free edge 0 the adjacent side portion of both sashesand also the accommodation of angular turns a, which form the terminalsof inwardly extending horizontal portions a of the sheet of metalforming the major portion of each side member..

The top rail B of the upper sash comprises two independent transversesections B B which at their tops have inward horizontal bends bterminating in short under turns b. This enables the sheet metal strip Bforming the top of the rail B, to be moved laterally at a pointrepresented by one of the ends of the sections B B to firmly engage theunder bends of said side sections through the medium of bends b, whichinterlock with B", and those of the section B, are so disposed that intheirinterlocked position they present a top surface for the sash Bwhich will closely conform to the under side of the lintel bottombetween the offsets a and a.

The lower portion of the sections B B as shown, are bent inward in theform of moldings and ,continuations, present upwardly converging flangesB terminating in narrow. horizontal outward bends t.

-may be shaped to provide an ornamental mo d ing 6 and plain front 6 thesection at the bottom of the rail having an inward bend b with anoverturn. At its op osite side said section inclines downwardly 'or aconsiderable distance in the direction of the rear of the window, andthen has a short rearwardly extending obli ue shoulder b from whichcontinues a furt 161 rearwardly inclined ortion b of the rear wall ofthe meeting rai a for- 'wardly extending horizontal bend b" having arearward overturn representing the free part of said sheet metal sectionat the rear portion of the rail. A transverse sheet metal strip B hasunder turns 6 and can be laterally slid from one end of the rail toengage the overturns threeof, and thus connect and brace said rail aswell as close the same at the bottom. It will be noted that here alsothe interlocking turns are so arranged that the external surface of therail bottom will be practically flush and present a finished appearance.The meeting rail 13 of the other sash, while presenting some of thecharacteristics of the companion of the top sash, differs somewhat inconstruction. In said meeting rail B of the to sash, the interlockingstrip B is necessar' y at the top. The oblique shoulder b is on thefront side of the to rail of the lower sash so that the front wall 0said rail closely conforms to the rear wall of the bottom rail of theupper sash when said up; per and lower sashes are in their closedpositions. Independent sections B and B forming the main parts of therail 13, have their lower parts conditioned similar to the sections Band B of the top rail of the uppersash, including outward bends to servewith a clencher I) applied the same as the clencher b.

The bottom rail 13 of the lower sash is of a single section of sheetmetal and is shaped at its top similar to the upper portion of the railB to provide the bearing B for the lower part of glass panel C,thefsheet metal section constituting the rail B being also shaped topresent the front and rear walls which when the lower sash is in itsclosed position extend down to the sheet metal section forming thesheathingof the sill. It will be seen that the front wall extends downin front of the shoulder a and terminates in an upward bend which fitsclosely against said shoulder. The rear wall depends down in closerelation to the shoulder a and terminates in an upward bend. A section Bis shaped to intimately conform to the upper surfaces between theshoulders a", a, as well as the incline a, and has bends which interlockwith those of the front and rear walls of the lower rail of the bottomsash.

- The upper and lower sashes are confined and guided in their slidingmovements by reason of their free edge portions being located within thebends a), a, a of the side members.

In case the free edge portions l), of the side rails of the sashes, areslightly longer than represented, such variation may be readilycompensated for by means of nuts e, which are soldered upon the terminalhorizontal portions of the sections A", the threaded shanks of longscrews a passing through openings therefor in the upward bends 0. of theside members and through the sections A and the nuts e connectedthereto. By simply turning the screws 0, in the proper direction, theplates A will be moved and held somewhat away from the bends a, and thusprovide for longer free edges of the side rails of the sashes.

The operation and advantages of the imroved window will be readily apreciated from the foregoing description. 'I l interlocked parts notonly provide simple structural features, but impart durability to thewindow. The presence or omission of the molding will be optional.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is,

1. In meeting rails for upper and lower window sashes, the meeting railof the top sash having its major art formed of a single section of sheetmetaf shaped at its top to present a bearing for the lower edge of theglass pane, said rail having a vertical front wall terminating in arearward horizontal bend with a forward overturn, the rear wall of saidrail embodying two rearwardly inclined surfaces with a shortintermediate obli ue shoulder, said rear wall havin a forward horizontalbend with a rearwar overturn, an independent section having edge turnsand adapted to he slid edgewise to engage its turns with those of themain part of the rail, the meeting rail of the other sash comprisingindependent front and rear sec- 1e several tions having upper horizontalbends with under turns and ower vertical flanges with outward bends, anindependent section having bends at its edges and adapted to be movedendwise for engaging its bends with those at the top of the sections toclose and constitute the top of said meeting 'rail, and a clencher adated to be slid edgewise "to interlock with tl ie bends of the flanges tofurther connect and'brace the independent sections relative to eachother as well as contribute to form a'bearing for the upper edge portionof a glass anel,' the forward'section of the meeting ra of the lowersash being configurated to intimat'elyeonform with the rear wall of thecompanion meeting rail. when thesashes are in their closed positions.
